Looks like lock is obly implemented for SMB1. Also, you seem to use a hardcoded fnum value of 0, for SMB2+ I seem to get 1, and for SMB1 it's worse, as you'll get a random number there.

Implement lock for SMB2?

I personally wouldn't care about a test for smbstatus output, that's an untested mess anyway. If we have something like stable JSON output, then sure.
